<?php $items = array(new \stdClass(), new \stdClass()); $udiff = array_udiff($items, $items, function ($a, $b) { $result = $a === $b; var_dump($result); return $result; }); var_dump($udiff);

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
